For those with this same toshiba satellite L15W-Bxxx and have constant freezing,
I have a work around for you. sudo nano -w /etc/default/grub pass these kernel arguments: GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=Linux acpi_call intel_idle.max_cstate=1 intel_pstate=enable video=i915" well, the most important two is intel_idle.max_cstate=1 intel_pstate=enable intel_idle.max_cstate=1 will allow your baytrail processor to idle, some reason the kernel doesn't know how to idle the CPU properly so it runs on full speed at all times, and bursting to its turbo speed under load hastens the overheating, with no way to keep the core cool, even when there is nothing really running, just ends with a frustrating hard lock, and resetting the power is the only way to recover, but there is nothing in the dmesg, kern.log, fail.log, etc. using MCE logs, it only says a thermal hardware event occurred. intel_pstate=enable this will allow you to set scaling frequency using thermald, sensor and tlp, (several guides on how to set these up, I can't sensors and pwm to detect any fans so if anyone has figured that out, let us know), but with these packages, my processor, when nothing intensive is going on it can scale between 500mhz to 2.16ghz on battery, and 1.5ghz-2.6ghz with ac in, and is able to shut down cores as need be as well. I set powersave mode for when its running on battery and performance mode when ac is plugged in.... I have not had a single issue with lock up and freezing anymore. So that ended my 6 months of frustration. But I still get "toshiba_acpi: Unknown event received 93" nonstop, but now my system isn't freezing within 15-180 minutes after bootup anymore, in that regard i'm pretty stoked. I'll upload my dsdt.dsl and ssdt*.dsl files, it shows some undefined values/errors the kernel receives from the motherboard EFI/bios, i'm not sure if this is what is causing issues, or if it even matters, but following a guide online that shows how to decompile the dsdt, there is a way to recompile it with the corrections, and supposed to solve any issues with the kernel communicating with the hardware on the motherboard, but my knowledge with this particular is rather thin as you can tell... so i'll add the attachments. hopefully someone can make heads or tails out of it -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1546092 Title: computer freezes frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-xenial/+bug/1546092/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
